Hi,I've noticed whilst playing with RNAV approaches that when I perform a go around, the FMS sometimes loses the perf data so it no longer computes approach speeds, despite it apparently having all the required data to do so.It also means I can no select a destination ("NOT ALLOWED"). Is this correct behavior?I've also noticed that if I do a touch and go, that again, the FMS thinks it landed and loses all the data. I can't believe this to be the case in reality.Best regards,Robin.

Happens to me too. The only way to get her to spit back out the Vapp speeds is to enter the altitude which you've leveled off at or the missed approach altitude as the cruise level in the init page.

NOT ALLOWED.Hmm....Best regards,Robin.

hmmm ok try rentering the dep and dest and try it again.

NOT ALLOWED.Tried that already...I'm not sure if it is a bug. Just doesn't make sense.I thought the FMS only reset when the engines were shutdown, and not simply in flight because it thought you arrived...Best regards,Robin.
